1600cc 3 plugs fail all at once
Hi all,
I was troubleshooting a no start in my engine. I did the timing, valve gaps, different dizzy, different ignition coil. I finally got it to start, but
it was only firing on 1 cylinder. I replaced all the plugs, and now she runs like a dream.
What would cause 3 plugs to fail all at once? I was driving the car fine the day before.

Crap plugs?
I read it on samba, so it must be correct.
Sometimes Volkswagen dealers sell spare parts. Amazing isn't it!

Bosch plugs fellas, made in Germany. I replaced them with Bosch made in Russia. The gaps are closer on the Russian plugs.

What do you mean the gaps are closer? The gaps are checked and set prior to fitting the new plugs, in almost 50 years I have never seen 3 plugs
collapse even in the old days the occasional porcelain used to crack from the heat and fall into the cylinder causing an intermittent miss mostly
under load.The thing that would foul 3 plugs is an over rich mixture possibly be caused by a sticking choke ,high float level,leaking needle and seat
or the accelerator pump discharge nozzle falling out.

I had 3 plugs fail (KLG) back in 1972 after 300kms. One completely and two misfiring. 1303Steve was with me on a trip to Providence Portal. I've also
had Champions fail out of the box.
I read it on samba, so it must be correct.

Hi
I do road service for a large motoring organisation, I get called to many late cars with fouled plugs. It usually happens when a modern car is started
and turned of too soon or just just incorrect staring technique.
It often happens when a person starts their car, moves it out of the garage, washes it, starts it again and puts the car away, the next start the
plugs will be fouled, I've had rotaries that I've had to tow around the block to unfowl plugs as cleaning them has no effect.
Most cars I usually only have to hold my foot flat while cranking to clear the plugs. Some cars I heat the plugs with a butane torch to clean the crap
of them.
When the plugs are fowled its usually accompanied by the motor sounding as if it has no compression, this is because the oil has been washed off the
bore by flooding.
Steve

the gap should still be 0.025 " or 0.63mm regardless or where the plugs are made
